Duke freshman Amile Jefferson's layup with 9:23 left gave the Blue Devils their largest lead to that point at 66-53. That came during a late 19-8 run that put Duke in control.

Logan Aronhalt pulled Maryland within single digits for the final time when his 3-pointer with 13 minutes left made it 58-49. Sulaimon countered with his sixth 3 to start the run, and Quinn Cook capped it with a jumper that put the Blue Devils up 20 for the first time, 77-57 with 4:39 left.

Cook finished with 11 points for Duke, which was coming off its most lopsided regular-season loss since 1984, a 90-63 beatdown at No. 25 Miami that will assuredly send the Blue Devils tumbling from No. 1.

The Terrapins hadn't allowed a conference opponent to shoot better than 38 percent this season. They would have kept that going had Sulaimon not turned this one into his personal shootaround.

He hit four straight 3-pointers and scored 13 points during a 15-5 run that gave Duke its first bit of breathing room. That burst included a four-point play and a deep 3 in transition that had coach Mark Turgeon calling time out to cool him off and drew "Holy `Sheed" chants from the Cameron Crazies.

His fifth 3 gave the Blue Devils their first double-figure lead, 32-22, with 6 1/2 minutes before halftime.
